Is there a way to change the result of an automated run?

I have a few automated runs that trigger each night, there are a few of our services which are a little flaky and cause fails.

I then sometimes need to manually rerun those fails, 99% of the time they pass.

In this scenario, I’d like to update the results of my automated run to show that things are passing. Is this possible?

No, you cannot delete individual automation test results, only complete automation runs (if you have the necessary privileges).
However, you can upload the results from the rerun to the same test run and so you will see that the test case passed the second time.

Best regards,
Alex
